Lady Helen was on the Balcony - she was there in the first appearance whilst the Queen was taking the salute.

Thanks; I've done a quick search on Google Images and found this photo of the royal family on the balcony- I spotted Lady Helen and her children on the right.

Is it because he was advised no to ride or that the Queen would have to ride alone without him this time, as the DoE is in hospital?
.

I'm confused by your question,

The Duke of Kent would have been at the parade today even if DOE had been there, he always is, however he had been advised not to ride due to his stroke earlier this year. Wbenson mentioned that he would have attended in a carriage.

With the DOE out of action it made sense for DOK to accompany The Queen.

Did anyone watch the coverage on BBC? While the crowds were walking down they showed a nice little piece put together about royal babies. They showed the queens children, grandchildren and then moved onto the great grandchildren from Peter Phillips. They showed Peter and Autumn first with Savannah out looking at the horses then a still black and white image of them with one of their daughters christening. I couldn't tell if it was Isla or Savannah. What did everyone think?

I saw it and I really liked the Phillips's photos. I wish they would've released the official photos.

I've never seen that picture before, nor have I seen that footage before.
